SOCIO-ECONOMIC ASSESSMENT OF COASTAL COMMUNITIES IN EAST FLORES MARINE RESERVES OF EAST NUSA TENGGARA PROVINCE, INDONESIA [PDF]

open access: yesRussian Journal of Agricultural and Socio-Economic Sciences, 2020
Marine reserves are marine protected areas with specific characteristic for the purpose of protection of fish species diversity and ecosystem. The purpose of this research to identify economic activities that can produce benefits as optimal as possible ...

Small marine reserves do not provide a safeguard against overfishing

open access: yesConservation Science and Practice, 2021
Marine reserves aim to protect harvested species within their boundaries and can therefore provide insurance against the effects of overfishing. To evaluate whether marine reserves are meeting this expectation, we compiled over 40 years of rock lobster ...

Increasing spillover enhances southern California spiny lobster catch along marine reserve borders

open access: yesEcosphere, 2022
The conservation benefits of marine reserves are well established but their contribution to adjacent fisheries via spillover is less certain and context‐dependent.

Marine reserves can enhance ecological resilience [PDF]

open access: yesEcology Letters, 2015
Abstract The goals of ecosystem‐based management (EBM) include protecting ecological resilience, the magnitude of a perturbation that a community can withstand and remain in a given state. As a tool to achieve this goal, no‐take marine reserves may enhance resilience by protecting source populations or reduce it by concentrating ...

Marine reserves with ecological uncertainty

open access: yesBulletin of Mathematical Biology, 2005
To help manage the fluctuations inherent in fish populations scientists have argued for both an ecosystem approach to management and the greater use of marine reserves. Support for reserves includes empirical evidence that they can raise the spawning biomass and mean size of exploited populations, increase the abundance of species and, relative to ...

Detecting larval export from marine reserves [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Marine reserve theory suggests that where large, productive populations are protected within no-take marine reserves, fished areas outside reserves will benefit through the spillover of larvae produced in the reserves. However, empirical evidence for larval export has been sparse.

Eco‐evolutionary dynamics of Atlantic cod spatial behavior maintained after the implementation of a marine reserve

open access: yesEvolutionary Applications, 2022
The effects of marine reserves on the life history and demography of the protected populations are well‐established, typically increasing population density and body size.

Our shifting perspectives on the oceans [PDF]

open access: yes, 2003
In the last 15 years new research findings have radically reshaped our understanding of human effects on ocean ecosystems. Here I describe five major shifts in perspective that reveal our impacts to be more severe and persistent than previously ...

Marine reserve effects on fishery profit [PDF]

open access: yesEcology Letters, 2008
Abstract Some studies suggest that fishery yields can be higher with reserves than under conventional management. However, the economic performance of fisheries depends on economic profit, not fish yield. The predictions of higher yields with reserves rely on intensive fishing pressures between reserves; the exorbitant costs of ...
